The invention relates to an isolated electromagnetic proportional balancing valve suitable for multi-pressure working conditions. The isolated electromagnetic proportional balancing valve comprises amagnetic circuit balancing device and a pressure balancing device. The
magnetic circuit balancing device comprises an outer magnetizer, a wire
package, a magnetic isolating ring, a static iron core, amain spring, a magnetic conducting cover, a proportional magnetic ring, an armature, a positioning spring and a pressing ring. The pressure balancing device comprises a valve body, a
valve stem, a valve core, a guide ring, a bottom cover, a large sealing ring, middle sealing rings and small sealing rings. According to the valve, the large flux leakage
magnetic circuit and proportional magnetic ring design is adopted, the electromagnetic force of the
electromagnetic valve can increase almost linearly, the balance of the electromagnetic force and the
spring force is realized, and the balance and stability of stress of the armature are ensured; and meanwhile the balance pressure design is adopted for a liquid path so that medium static pressure and medium
dynamic pressure can be cancelled out, the stress state of the armature has no connection with the pressure, the
working pressure range can be enlarged, and the isolated electromagnetic proportional balancing valve is suitable for special working conditions of the pressure changes and fluctuations.
